            Bug ID: 140746
           Summary: Trying to resize the sidebar results in the sidebar
                    jiggling and LO locks up completely.
           Product: LibreOffice
           Version: 7.1.0.3 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: UI
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
When I start LO (Writer, Calc, ...) and try to resize the sidebar the border
where I drag it starts to jiggle left and right (like it doesn't know how to
deal with my mouse input) and it locks up completely, still showing the
left-right-arrow you get when hovering the border where you drag it, but
everywhere in the program window. Then I have to kill the process to get it to
close.

I think this is caused by the scaling factor I've set in Windows for my
Monitors (3x 4k at 200%). This would explain why the mouse input might be
interpreted the wrong way (some part doesn't consider the scaling factor
correctly or something like that).
I've also tested disabling the scaling (i.e. set to 100%) temporarily and this
specific problem is gone (I get a different one instead where the mouse pointer
is in a completely different position than the sidebar border, but I think this
is caused by not logging out of Windows and back in again to apply the new
scaling factor properly [known Windows bug]). It might be that this only
happens when using a multi-monitor setup, at least that's what I have here.

This problem occurs in LO 7.1.0.3, and I installed 7.0.4.2 as a replacement now
until this is fixed. There I also can't resize the sidebar correctly (only
about 20px movement left to right), but at least it does not lock up
completely.

Steps to Reproduce:
1. Set your Windows display scaling to 200% (a 1440p or 4k monitor helps for
that)
2. Start LO 7.1.0.3
3. Resize the sidebar

Actual Results:
LO locks up and the sidebar jiggles.

Expected Results:
Sidebar resizes correctly.


Reproducible: Always


User Profile Reset: Yes
